This invention pertains to pumping aptns is shown with a grip hangerframe 2 paratus and has to do with an improved and firmly attached in asuitable manner, as by efficient means for connecting a pumping screwstl, and a cable snpportinQ,- member a grip, which usually carries suckerrods, assembled on the frame and carrying` a cable with a walking beamof a pump apparatus. which is connected to a suitable pinnpin,e` 60 Itis well known in the operation of pump io (not shown) which in turn isadapted apparatus that the end of the walking beam isp the ends of oneor more sucker rods. reciprocates in a path which is an arc of a beenfound by experience that the circle, and that tbe sucker rods, whichdecab e support men'iber l must be of sufticient pend upon the walking`beam for their movewidth. to straddle the walking` beam, ande 65 ments,reciprocate in vertical paths. lt is, therefore, .l have shown in l thetherefore, desirable in providing the most efpreferred construction ofmy cable supportficient connecting means between the beams ing member.In this support I provide a and the rods to design the to reduce thegroojfe tl having an inner groove 7 whicb i5 wear and friction to aminimun'i, while at readily receives and definitely positions a 70 theSam@ time permitting quick and easy 21.0- Slligle Qabie, but WillCl iSadapted t0 lQCeiV sembly and disassembly of the connection.

A reinforcing brace a connection between thewalking beam and ii 0f Suitable COnStluction is arranged to -0 the rodsin which is included a novel grip connect the ends of the groove portionofthe 55 hanger of sturdy construction and an ar- Gable Supportingmember, thereby preventrangement of the parts thereof which reim);collapsing` of these end portions, as the duces friction and wear to theminimum. lt Cble, when normally carrying .its load, has is a further aimof this invention to provide Considerable tendency to squeeze thesupportan improved construction @-5 the parts that ing` member. Thiscable supporting member S0 will permit ready attachment and detach- 1Sjicvided with a bearing` edge 9, preferably ment of the workingconnections between the Of Sharp Ol V-Shaped construction, some'- Suekerrods and the walkingbeam, times known as a knife edge.

Preferably, this trame 2 is constructed With two upstandingportions 111 and 15 arranged to receive a suitable seat 16 across thetop edges thereof. rlfhe underside et the seat 16 may be designed in anysuitable manner to engage the upstandinaportions 14 and 15, usuallyproviding relatively large bearing` surfaces. My preferred constructionJfor accon'iplishing this end is to provide grooves 17 in the seat 15and to form rounded parts 18 and 19 at the top et the upstsmdingportions1l and 15 respectively. This seat is movable in relation to the frame,and I prefer to pivotally attach the seat to the trame by bolt Q0, asshown in Figs. 2 and 8. Suitable lugs 21 which receive the pin 2O engagethe sides ot tire upstanding` portion 1li, thus preventing, longitudinalmovement of the seat.

The top surface 22 et th seat member is preferably concaved to ibearing` surface tor the reception oj bearing edge 9 of the cablesuiiporting member, as illustrated in Fig. 3.

By reason of maning this concaved surface et radius, it is Yound thatthe bcarin` edge 9 settles the lowermost position and has a relativelysmall area. ont contact therewith, thus reducing; the Wearingand the`friction to a minimum.

1t Will be seen from the foregoing description that the cable supportingmember may be readily assembled in the frame 2 by raising,- the seat a,thus permitting brace 8 to be int-reduced in the trame between 'the twoupstanding portions 111 and 15, and thereatter closing the seat acrossparts 19 and iermitting bearing surface 9 to engage the seat, therebyholding the cable supporting member in etlicient engagement with thetrame. ritt the same time shoulders 10 engage the edn'es ot the scat,thus preventing loinritudinal movement of member Ll over the seat 16. ltwill also be readily seen that in dismounting this improved grip hangerthat cabl supportin Q,` member 4t may be litted. trom the :trame 9,Without requiring special attention, and without requiring that thetrame 2 be removed from the Walking' beam.. understood that severalmodicaions and changes may be made in the construction et the improvedgrip han ger here-- in illustrated and described which Will reduce Wearand friction, and which Will permit ready assembly or disassembly of thepart-s, but such changes are considered as being Within the scope ot myinvention as outlined by the subjoined claims.
